REFRIGERATING APPARATUS.

application filed. June, 18, 1925. Serial No. 38,029.

This invention relates to a refrigerating process and apparatus therefor, and has for its object to provide, in a manner as hereinafter set forth, arefrigerating process and 5 apparatus whereby refrigeration is obtained through the medium of ventilation and washed air.

A further object of the invention is to provide, in a manner as hereinafter set forth,

1 a refrigerating .process and-apparatus whereby excessive shrinkage, as well as the accumulation of ice in the bunkers is eliminated.

A further object of the invention is to pro vide, in a manner as hereinafter set forth, ,a

1 refrigerating process and apparatus whereby the air' in a chilled or storage room can be continuously freshened during the operation of refrigeration, in accordance with this invention, under'such conditions materially lessening the contamination of the air in suchroom to overcome any material reduction in its refrigerating action. I

Further objects of the invention are to provide, in a manneifias hereinafter set forth,

, a process of refrigeration and ineans for carrying out the process and with such means comparativelysimple in its constrution and arrangement, strong, durable, thoroughly efficient in use, readily installed and comparatively inexpensive. v

l/Vith the foregoing and other objects in view, the invention consists of the new, novel and improved method of refrigeration, as well as the apparatusfor carrying out the process, as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications with respect to the apparatus shown falling within the scope of the claims hereunto appended can be had. v

In the drawings, like reference characters denote corresponding parts throughout the several views, and in which i Figure 1, is a'fragmentary view, in cross section of a compartment structure or building, showing the arrangement therewith 0f the elements of a refrgerating apparatus in accordance with this invention.

Figure 2, is alike view taken at right angles to Figure 1.

Figure 3, is atop plan view partly in'section and broken away. 6 Figure 4-, is an enlarged fragmentary view in cross sectlon.

The drawings illustrate, by way of example, the adaptation of arefrigerating apparatus in accordance with this invention with respect to a chill room and a storage room,

but with the elements of the apparatus shown generally'and not specifically withrespect to the storage room, however the specific construction and arrangement of the 1 elements of the apparatus are shown specifically with respect to the chill room.

In the drawings, 1 denotesconventionally a compartment structure or building pro- 'vided with a basement 2, a chill or refrigerated room 3, a refrigerant or refrigerating apparatus receiving compartment 4 arranged at -the top of a chill room 3, a storage room 5, a refrigerating apparatus receiving compartment 6, arranged at the top of the storage room 5, ventilators 7 opening into" refrigerating space, after which the lighter The of such air escapes through the ventilators 7 or 8, and the heavier or fresher of such air is acted upon by the refrigerant discharged from the pipes 25 and returned to the chill room 3. The foul air. that escapes through the ventilators 7 or 8 is replaced by a fresher or heavier air coming through the ventila; tors 7 or 8. The ventilators 7 or-'8 afford a means forthe foul air to escape and for the same'to be replaced by fresh air entering through the same. I The compartment 4, as well as the compartment 6, is provided through the medium of a centrally disposed transversely extend ing'. beamlO upon which islnounted a series of longitudinally extending beams or joists 11, arranged in spaced relation and further spaced from the side walls of the compartment. The outer beams of theseries 'ofbeams 11 are indicated at 12,12 and which are spaced from the side walls of the compartment to provide vertically disposed air' passages whereby they-light or warm air from the chill room, or from the storage room, will passinto'the compartment 4, or 6,

' of oppositely disposed spaced bunkers each includinga vertically disposed side wall 13 and a downwardly inclined floor 14 and with the inclination of the floor 14 extending towards the longitudinal center of the compartment 4. The side walls 13 of the bunkers extend from one end to the other end of the compartment and said side walls 13, as

well as the bottoms 14, of the bunkers, have arranged therein, as well as throughout, a body of insulation, preferably formed of cork, and indicated at 15. The floors 14 extend at opposite inclinations with respect to each other and further each has its inner.

endgterminate at one side of the longitudinal center of the compartment 4. Each of the bunkers include a plurality of supports 16 which are interposed between the bottom 14 and the series of beams 11, and the side wall 13, of each bunker, forms in connection with the side walls of the compartment 4 a continuation of the air passage 15 and the latter terminates at its upper end at a point rein any suitable manner.

moved from the top of the compartment 4, due to the fact that the side walls 13 of the bunkers do not extendto the said top.

Extending longitudinally of the compartment 4 is a pain of spaced brine tanks 17 18, which are arranged over the floors 14, as well as being spaced therefrom and from the Walls 13. Arranged in the tank 17, as well 'as the tank 18, is a refrigerant coil 19 and which is of sufficient capacity to chill the sodium chloride brine circulating through tanks 17 and 18 to the temperature necessary to chill the air that is washed or passes through the dripping sodium chloride brine discharged from the tanks 17 and 18 through a means to be presently referred to. The refrigerant can be supplied to the coils 19 Gonnected to the tanks 17 and .18 and extendingtransversely ofthe compartment 4 is a header 20 for one end of a longitudinally extending set of-tlischarge pipes 21. and connected to the other end of the tanks 17 and 18 and extending transversely. of the compartment 4 is a header 22* for the other end pf the; series of discharge pipes 21. The construction of the header is better shown in Figure 4 and it is formed of a series of pipe branches 23 connected together by inverted 'T-coupl-ings 24," and tothe vertical leg of each of which is connected a vertically disp sed pipe branch 25 connected by a cou- I pling 27 to one end of a discharge pipe 21 and each of the latter is provided substantially throughout, at its top, with a length- 30 connected to an end of a brine tank. The

feed pipes 30are arranged at the lower portion of the ends. of the brine tanks and extend inwardly therefrom for the purpose of supporting, in connection with the pipe branches 29, the headers above the bottoms softhe brine tanks and further in spaced relation with respect to the inner sides of said tanks. 1

The vertical pipe branches 25 of each header are arranged in spaced relation and the pipe branches 25, of one header, are posi tioned in parallelism with respect to the pipe branches of the other header and each panof parallel pipe branches 25 have arranged therebetween a longitudinally extending fiat substantially narrow, rough board 31 which constitutes a deflector" for the brine as it is discharged or overflows from the pipe 27. The boards 31 are arranged against the pipes 27 and are connected therewith in any suitable manuer and are of a length slightly less than the length of said ipes, but the boards 31 are of greater width'tha n the diameter of the pipes 27 whereby, when the boards 31 are-mounted in position they will project laterally from each side of the said pipes 27. The boards 31 are positioned in sidewise arrangement, but spaced from each other.

Extending transversely of the compartment 4 and arranged over, as well as being spaced from the pipes 27, is a feed pipe 32 for supplying the brine to the tanks 17 and 18 and for such purpose one end of the pipe 32 opens into a valved inlet pipe 33 which communicates with the tank 17, through the top thereof. Leading from the pipe-32 and communicating with the tank 18, through the top thereof, is a valved inlet pipev 3K The pipe 32 opens into. a supply pipe which extends into the basement 2 and communicates with a pump 36 which is employed for pumping the brine from a reservoir or tank 37 arranged within the basement 2 andsaid reservoir or tank 37 has leading thereto a conducting pipe 38 for the discharge of the overflowing brine from the pipes 27. Secured to theinner end of each of the bunker floors 14 is a longitudinallv extend of pipes 27 is an .invertedV-shaped deflector. of the louvre type and which is indicated at 40, and with the sectionsthereof disposed at a. downward inclination. The lower sections 41 of the deflector 40 extend over the top edges of the opposed sides of the troughs 39.

.ers, from there into the slotted pipes 27 and overflows on to the rough boards 31, thence dripping from the rou 11 boards 31 on to the insulated bunker oors 14 and flows into the collecting trough 39 and from which the brine is discharged by the pipe 42 into the pipe 38 which leads to the tank or reservoir 37. As the brine drips from the board 31 it.wil1 wash and cool the air and thecoolair will flow through the louvre deflector 40 into the chill room 3. 'The air n the room will take on heat and rise to the bottom of the. bunker floors 14, thence to passages'l t' from there to the ventilators 7, which will permit the lighter air-to es cape, under such conditions causing the air in the chill roomfto be freshened and lesscontaminated. The air that passes the ventilators will be drawn into the dripping brine and will pass through the course as aforesaid and the foregoing operation refrigeration is o tained by a ventilated and washed air process. The foul air which'has escaped through the ventilators? or 8 is replaced by fresh air entering through the a same, as hereinbefore set forth.

It is thought the many advantages, by the process of refrigeration and apparatus therefor, in accordance with this invention, can be readily understood and although the preferred. embodiment of the apparatus is as described in the claims, yet it is to be understood that the changes in the details of construction can be had which will fall within the scope of the invention as claimed.
